TIA 942
Welcome to TIA-942.org
The ANSI/TIA-942 is a quality standard for data centers. The standard specifies requirements for data centers including single tenant enterprise data centers and multi-tenant Internet hosting data centers. The topology presented in the standard is applicable to any size data center and covers all physical infrastructure including, but not limited to, site location, architectural, electrical, mechanical, fire safety, telecommunication, security and other requirements.
Data centers can be reviewed and certified for conformity to the requirements of the ANSI/TIA-942 standard.
About Data Centers
With few exceptions, companies today rely heavily on IT for the delivery of business-critical services often directly to the end consumer. It is therefore vital that the mission-critical Data Center is designed, maintained and operated with high-availability and efficiency in mind.
When building and operating a data center one wants to ensure that it has been designed and built based on globally accepted standards, yet have the flexibility to adapt to the business requirements.
Survey results show that in more than 78% of the cases, data center operator/owners chose the ANSI/TIA-942 standard when it comes to designing and building a data center.

The Telecommunications Industry Association (TIA) ANSI/TIA-942-A Telecommunications Infrastructure Standard for Data Centers[1] is an American National Standard (ANS) that specifies the minimum requirements for structured cabling work defined in TIA/EIA-568, and is often cited by companies such as ADC Telecommunications[2][dead link] and Cisco Systems.[3][dead link] The standard was updated with an addendum ANSI/TIA-942-A-1 in April 2013 from the TR-42.1 Commercial Building Telecommunications Cabling Subcommittee, the formulating group that oversees development of the standard.[4] The Telecommunications Industry Association does not offer certification programs or certify compliance to TIA standards. In many cases, there are other organizations and consultants that can provide those services. However, TIA does not certify these organizations or consultants. This is similar to how organizations like ISO operate where they rely on Certification Bodies to ensure that there is oversight over organizations performing such activities.

TIA-942 Certification
ANSI/TIA-942 covers the telecommunications infrastructure and all other aspects of a mission-critical data center, such as the site location, architectural and physical structure of the building, electrical and mechanical infrastructure, fire safety and physical security.
The TIA-942 certification scheme establishes Conformity Assessment Bodies (CABs) deemed competent to verify data center conformity with the standard.
Within the TIA-942 certification scheme, CABs will be accredited through the independent evaluation of an organization against recognized standards to ensure their impartiality, competence, and consistency. The accreditation process established for this scheme relies on ISO 17020/17021 - a uniform approach accepted and implemented around the world to determine the competence of an audit organization.

ANSI/TIA-942 Ready Certification
ANSI/TIA-942 Ready Certification indicates that a product, typically a modular data centre such as pre-fabricated data centre Edge Data Centre/Module or a Container based data centre product has been designed in accordance to the requirements of the ANSI/TIA-942 standard for the respective Rating level. The TIA-942 Ready Certification will review all aspects under scope of the module to ensure it meets the requirement of the TIA-942 for that particular scope. This certification will ensure that once the modular data centre solution has been placed in the appropriate environment that it will meet the indicated Rating level. The TIA-942 Ready Certification has a few distinct advantages for manufacturers of modular data centre solutions and their customers;
Pre-validation of conformity to TIA-942 of the modular data centre at the manufacturer level Reduction of certification time due to pre-validation process Discounted cost for full ANSI/TIA-942 design (DCDV) and site/facility (DCCC) certification
EPI is the world's first and so far the only ANSI/TIA-942 CAB authorised under the official TIA-942 Accreditation Scheme from TIA to provide data centre conformity audit services to the ANSI/TIA-942 standard. EPI is also incorporated as a CB (Certification Body).

Chapter 1: Introduction
Background and History of Data Centers
Data centers are critical infrastructure facilities that house and manage the information technology (IT) equipment and systems that power our modern digital world. They have evolved significantly over the years, from early computer rooms to highly sophisticated, mission-critical facilities. The history of data centers can be traced back to the mid-20th century when the need for centralized computing and data storage emerged.
In the early days of computing, businesses and organizations relied on mainframe computers that required specialized environments to operate efficiently. These early computer rooms laid the foundation for what we now recognize as data centers. As technology advanced, the size, complexity, and importance of data centers continued to grow.
The explosion of the internet, the proliferation of digital devices, and the advent of cloud computing have all contributed to the exponential increase in the demand for data center services. Today, data centers play a pivotal role in enabling businesses to deliver online services, store vast amounts of data, and support the global digital economy.
Need for Data Center Standards
The rapid expansion of data center infrastructure brought about the need for industry standards and best practices to ensure the reliability, availability, and performance of these facilities. Data centers are expected to operate 24/7 without interruption, making downtime extremely costly and detrimental to business operations.
Without standardized guidelines for data center design, construction, and operation, there was a risk of inconsistency and variability in the quality of data centers. This lack of standardization could lead to inefficiencies, increased risk of downtime, and compromised data security.
Overview of TIA-942
The Telecommunications Industry Association (TIA) recognized the need for a comprehensive standard that could provide a framework for designing and building data centers to meet the highest standards of performance and reliability. In response to this need, TIA developed the TIA-942 standard.
TIA-942, titled “Telecommunications Infrastructure Standard for Data Centers,” is a globally recognized standard that defines the minimum requirements for the design and construction of data centers. It covers various aspects of data center infrastructure, including site location, architectural design, electrical and mechanical systems, cabling, and security.
TIA-942 is a critical tool for data center professionals, including architects, engineers, project managers, and facility managers. It provides guidance on creating data centers that can meet the demands of modern IT environments, including high availability, scalability, and energy efficiency.
